Pipe Organs

My first real job was at Livermore. Thanks mostly to Livermore I encountered a bunch of early computers. Here are notes on some of those machines by Seymour Cray and more from IBM, and how they divided.

Later I was at Tymshare where we did several interesting things such as Tymnet. We also did major enhancements to available operating systems:

In each case we hardened the security features, added accounting, adapted the system to Tymnet. We added features to the 940 and PDP-10 would later show up in Unix.
